Hello Gad,

On one occasion when it stopped working (due to rain?) We had an IBM
technician connecting some sort of electronic device to the S/36 side of
that Twinax line and saying "There is a short cut / disconnection 5 hundred
meters down the line" we went there and found a faulty Twinax nipple
connection. (luckily it was in a cables pit)

He was using a TDR device:

This functionality today is integrated at least with Cisco Catalyst Class
Ethernet Switches.

:wq! PoC
